Data from the largest urban air monitoring program of any U.S. city show annual average levels of fine particulate matter (PM 2.5), nitrogen dioxide (NO2) and nitric oxide (NO) have declined 43%, 39% and 56%, respectively since 2009. Source: Department of Health and Human Services

Traffic-related air pollution

Traffic is a major source of air pollution in New York City, especially in densely populated areas with high levels of vehicle traffic. According to a report by the New York City Department of Health and Mental Hygiene, an estimated 2,700 premature deaths and 100,000 emergency department visits and hospitalizations each year in the city are attributed to traffic-related air pollution.

Disparities in exposure

Air pollution is not evenly distributed across New York City, and low-income communities and communities of color are often disproportionately exposed to higher levels of pollution. According to the New York City Community Air Survey, neighborhoods with high poverty rates and high percentages of people of color have higher levels of PM2.5 and ozone than wealthier and whiter neighborhoods.

Ozone

According to the New York City Community Air Survey, the annual average ozone concentration in the city was 28 parts per billion in 2019. This is down from 34 parts per billion in 2008, but still higher than the national standard of 15 parts per billion. Source: Community Air Survey

√ Census & American Community Survey

Housing units
The ACS collects data on the number and characteristics of housing units in New York City. Housing conditions can affect indoor air quality, and households located near sources of outdoor air pollution may have higher exposures.
Commuting patterns
The ACS collects data on commuting patterns, including mode of transportation and commute time. Commuting can contribute to air pollution, particularly through emissions from vehicles.
Income and poverty
The Census collects data on income and poverty levels in New York City. Low-income communities and individuals may be more vulnerable to the health impacts of air pollution, as they may live in areas with higher levels of pollution and have limited access to healthcare.
Demographic characteristics
The Census and ACS collect data on demographic characteristics such as race, ethnicity, age, and gender. Some studies have found that certain racial and ethnic groups, such as Black and Hispanic communities, may be disproportionately exposed to air pollution and have higher rates of related health conditions.

"Inequitable Exposure to Air Pollution from Vehicles in New York State: Who Bears the Burden?"

Tailpipe emissions from cars, trucks, and buses are a leading source of harmful air pollution in New York State. This pollution has a significant impact on the health of the region’s residents, and varies greatly geographically and across different types of communities.

THE NEW YORK CITY CARBON CHARGE ("NY3C")

Fordham Environmental Law Review. This paper seeks to provide a blueprint for unlocking municipalities’ latent power to regulate carbon emissions within their jurisdictions through the use of a carbon charge. It uses New York City as a case study.

"New Jersey: A Case Study of the Reduction in Urban and Suburban Air Pollution from the 1950s to 2010"

This paper traces the changes in air pollution in New Jersey as a case study, demonstrating the impact of local, state, and federal strategies to control emissions of pollutants and pollutant precursors from the 1950s until today. 

"Short report: Children living in areas with more street trees have lower prevalence of asthma"

The prevalence of childhood asthma in the USA increased by 50% from 1980 to 2000, with especially high prevalence in poor urban communities. Street trees were associated with a lower prevalence of early childhood asthma. 

√ Key Issues

Particulate Matter (PM) Pollution
PM pollution, which is made up of tiny particles in the air that can be inhaled into the lungs, has been a persistent issue in New York City. Sources of PM pollution include vehicles, power plants, and other industrial facilities. PM pollution has been linked to a range of health problems, including asthma, heart disease, and premature death.
Ozone Pollution
Ozone pollution, which is formed when pollutants from vehicles and other sources react in the presence of sunlight, has also been a significant issue in New York City. Ozone pollution can cause respiratory problems and has been linked to increased hospitalizations and emergency department visits.
Traffic Congestion
Traffic congestion is a major source of air pollution in New York City, particularly in areas with heavy traffic. The city has implemented several initiatives to reduce traffic congestion and promote alternative modes of transportation, such as cycling and walking
Environmental Justice
Air pollution disproportionately affects low-income communities and communities of color in New York City. These communities often live in close proximity to industrial facilities, highways, and other sources of pollution. Addressing environmental justice concerns has been a key issue for many organizations and policymakers working on air quality issues in the city.
Climate Change
Climate change is expected to exacerbate air quality issues in New York City, as higher temperatures and more frequent heatwaves can increase the formation of ozone pollution. Additionally, extreme weather events such as hurricanes and floods can lead to releases of air pollutants from industrial facilities and other sources.
